Wireless temperature measurement and online monitoring system for high-voltage switchgear

Wireless temperature measurement and online monitoring system for high-voltage switchgearProduct Introduction

The switchgear partial discharge online monitoring system is used to detect, analyze, and continuously monitor partial discharge signals in high-voltage switchgear. The monitoring data is uploaded in real-time to the remote backend to achieve online diagnosis and warning of the insulation status of the switchgear.

Mainly used in high-voltage switchgear scenarios.

Wireless temperature measurement and online monitoring system for high-voltage switchgearKey Features:

Multi channel wireless temperature measurement real-time data display, capable of receiving up to 240 channels of temperature data.

It has the function of configuring device parameters and can perform main parameter programming settings.

The microcontroller and communication chip are respectively made of industrial grade chips; Has better stability and anti-interference ability in data transmission.

Under the condition of ensuring usage distance, ultra-low power consumption design is adopted, and the sensor battery power supply time is 5-8 years.

Equipped with a display interface and RS485 communication interface, it is a conventional temperature measurement terminal without display, and can be optionally equipped with a LCD host.
